1.
The long term effects of prolonged use of electrical stimulation are unknown.
2. Stimulation should not be applied over the neck. Severe spasm of the muscles may occur and the contractions may be strong
enough to close the airway or cause difculty in breathing. Stimulation over the neck could also have adverse effects on the heart
rhythm or blood pressure.
3. Electrodes used for electrical stimulation should not be applied across the chest because the introduction of electrical current into the
chest may cause rhythm disturbances to the heart.
4. The effects of stimulation of the brain are unknown. Therefore, stimulation should not be applied across the head and electrodes
should not be placed on opposite sides of the head.
5. Electrodes should be applied only to normal, intact, clean skin. Electrodes should not be applied over open wounds or over swollen,
infected, or inamed areas or skin eruptions, e.g., phlebitis, thrombophlebitis, varicose veins, etc.
6. Electrodes should not be shared with other persons. Each person should have their own set of electrodes; otherwise, undesirable
skin reactions may occur.
7. Self-adhesive electrodes should be replaced if they no longer stick rmly to the skin.
8. Stimulation should not be applied when in the bath or shower.
9. Safety of powered muscle stimulators for use during pregnancy has not been established.
10. Marc Pro should not be used while driving, operating machinery, or during an activity in which involuntary muscle contractions may
put the user at undue risk of injury.
11. Do not use the device in humid atmosphere (sauna, hydrotherapy, etc)
12. Caution should be used for patients with suspected or diagnosed heart problems.
13. Caution should be used when applying the device over a menstruating uterus.
14. Caution should be used when applying the device over areas of skin that lack normal sensation.
15. Operation in close proximity to shortwave or microwave therapy may produce instability in the output of the device.
16.
Simultaneous connection to h.f. surgical equipment may result in burns at the site of stimulator electrodes and possible damage to the device.
17. To ensure proper use and to mitigate the possibility of interference, avoid placing in close proximity to other electromagnetic devices.
